Title: Improvements in automatic firearms
IPC: F41A3/32
Filed: 1947-07-15
Abstract: 631,038. Automatic firearms. ZBROJOVKA BRNO, NARODNI PODNIK, and KYNCL, J. July 15, 1947, No. 18881. Convention date, July 15, 1946. [Class 119] An automatic firearm has, in combination (a) a breech-block mechanism in which the breech block moves back a short distance v before becoming positively locked and in which a breech-block carrier is accelerated, together with the breech block through the distance v by the pressure of gases acting against the base of the cartridge ; and (b) grooves in the walls of the cartridge chamber to enable propellant gases to reach the external surface of the cartridge case of the discharged round. In the construction shown the breech block 3 and its carrier 5 recoil through the distance v together when a shot is fired, the breech block then becoming positively locked by a fixed support 6 while the carrier continues rearwards against the action of the spring 8. Release of the breech block is eventually effected by the engagement of noses 10, 11 on it and the carrier respectively. Firing is effected by the action of a hammer 7 on the firing pin 4 whose rear end projects through a hole in a part of the carrier. The propellant gases reach the external surface of the cartridge case by way of grooves 9 in the cartridge chamber. The clearance v may be regulated by a suitable choice of the breech block or support 6, by axially adjusting the barrel, or by transversely moving the support when this is wedge-shaped. The support may alternatively move through the distance v against the pressure of a spring acting on the support, or the breech block may bear on a narrow flat spring projecting from the locking surface of the support. The Specification as open to inspection under Sect. 91 refers also to the grooving of the cartridge case. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to devices for collocating substantially rectangular packages
IPC: B65B35/44
Filed: 1949-07-19
Abstract: 692,120. Packeting-machines. MASON, J. A. and MOLINS MACHINE CO., Ltd. July 11, 1950 [July 19, 1949], No. 19001/49. Class 94(i) [Also in Group XXX] Apparatus for collocating substantially rectangular packets emerging from a vertical stacker comprises a device adapted to engage the top packet and remove it by a substantially horizontal movement on to a conveyer which is movably supported and the position of whose packetreceiving surface is regulated by a feeler which engages the top surface of said packet. As shown, completed packets 1 are fed upwardly through a vertical stacker 2, of the type described in Specification 615,610, wherein the wrapper seams are heat-sealed. The packets are transferred in succession to an endless conveyer unit 21 (see Group XXX), pivotally mounted at 23, by a reciprocating arm 3 which carries a pivoted, spring-loaded pawl 4 and is pivoted to a bellcrank lever 10 oscillated by a crank 12, the pawl being formed with an inclined surface 14 which rides over the next packet on the return stroke. The arm is urged downwardly by a light spring 15 and carries a roller 16 which engages the top packet during the operative stroke, whereby the arm is automatically adjusted to compensate for slight variations in the height of the stack. An extension 17 of the arm carries a roller 18 which engages a cam track 19 to locate the arm on the return stroke. To ensure that only one packet at a time is transferred from the stack, an angle-shaped stopper plate 33 is adjustably secured to the conveyer unit, the vertical arm 34 of this plate forming part of the fixed wall 37 of the stacker. The remaining three walls, including the wall 38, are movable inwardly and outwardly as described in Specification 615,610. The right-hand end of the conveyer unit is urged downwardly by a spring 40 and is located from the top of the stack by a roller 36 which is adjustably secured thereto and engages the upper surface of the top packet, so that the upper surface 35 of the plate 33 is maintained just below the undersurface of the top packet notwithstanding small variations in the height of the stack. The walls of the stacker are closed during the operation and return strokes of the arm 3 so that the conveyer unit is held in position by the pressure on the wall 34, and when the walls open to allow another packet to be fed upwardly through the stacker the end of the conveyer unit moves downwardly until the roller 36 engages the next packet.

Title: Improvements in electrical signalling systems employing sampling arrangements
Inventor: DAVIS JOHN CHRISTOPHER HAMMOND
IPC: H04J3/10
Filed: 1962-05-17
Abstract: 1,037,676. Transistor pulse-handling circuits; pulse-code modulation. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 9, 1963 [May 17, 1962], No. 19108/62. Headings H3T and H4L. In a pulse-code-modulation system wherein the amplitude of each pulse of a pulse train corresponds to the amplitude of a corresponding " sample " of an input waveform, the pulse train is applied to a circuit which delivers an output in which the amplitude of each pulse is maintained during the interval subsisting until the occurrence of the next successive pulse, a switching pulse occurring synchronously with each sample pulse permitting a capacitor to charge to the level of the sample pulse, the capacitor thereafter being isolated so that its charge is maintained until the next switching pulse occurring synchronously with the next sample pulse is applied to the circuit. In Fig. 1 a switching pulse occurring simultaneously with each sample pulse PAM is applied to the base of normally non-conducting transistor VT5 to render it conducting for the duration of the sample pulse. Depending upon whether the sample pulse is more or less positive than the immediately preceding sample pulse (which determines the state of charge of capacitor C4) transistor VT3 is rendered conducting or left non-conducting. In the former case the current from VT3 charges C4 positively until an equilibrium state is reached with all the current from VT3 flowing through VT5; in the latter case the capacitor discharges through transistor VT5 until transistor VT3 commences conducting and the same equilibrium condition is attained. In an alternative circuit, Fig. 2, designed to reduce effects of leakage currents transistors VT3 and VT4 are both normally conducting. The application of a sampling pulse sending the base of transistor VT4 positive with respect to its emitter switches that transistor off and diverts the current from transistor VT3 into capacitor C6. If the sampling pulse is of insufficient amplitude to switch off transistor VT4, capacitor C6 discharges through transistor VT7 to which the switching pulse is applied until transistor VT4 comes into conduction and an equilibrium condition is attained. Normally non-conducting rectifier MR5 prevents discharge of the capacitor in the interval between pulses; rectifier MR10 prevents the application of an excessive reverse emitter-base bias to the transistor VT4.

Title: Improvements in filter press
IPC: B30B9/04
Filed: 1938-06-28
Abstract: 512,536. Presses for separating liquids from solids. BAUSMAN, A. L. June 28, 1938, No, 19111. Convention date, Aug. 5, 1937..[Class 46] In a press having a series of plunger-bearing plates mounted in column formation between a resistance head and a hydraulic ram, a series of rings being interposed one between each pair of plates, each ring slidably receiving the plunger of a bearing plate, hydraulic means operable independently of the ram are provided for forcing all the rings against the rear faces of the plates to seal the press chambers formed in the rings, during the filling of the chambers. In the construction shown, a number of press units are mounted between a ram 28 and a resistance head 21, each unit comprising a plunger 53 fixed to a plate 52 and a ring 54 in which the plunger is slidably engaged. Except for the end plate 52<1>, all the plates and all the plungers are formed with circular series of perforations communicating with circular and radial grooves in that face of each plunger which abuts against a plate 52, the radial grooves leading to the lower portion of the periphery of each plunger. Each plunger and plate 52 carries a filter pad 60 consisting of an inner metallic screen of course mesh and an outer metallic screen of very fine mesh. The liquid to be pressed is supplied to the chambers 55 through axial passages 68, 67. The plates are supported for sliding movement by means of links 42, 45. The links 42 have tongues 43 engaged in grooves in rails 39, and the links 45 have tongues 46 engaged in grooves in the links 42. Hook-like ends 48, 49 are formed on the links 42, 45 respectively. In order that each ring 54 may be pressed tightly against the plate 52 of the next unit hydraulic jack devices are provided, Each ring 54 is provided with four cylinders 80, each receiving a piston 81. Liquid under pressure supplied through pipes 86 and a flexible pipe 87 from a manifold 88 forces the pistons 81 against the plunger-bearing plate 52 of one unit and thereafter moves the ring 54 tightly against the plate of the next unit. A relief valve 90 is provided adapted to open on excess pressure being obtained in the manifold 88. At the end of the pressing operation the plates 52 are spread apart by means of the links 42, 45 and the rings 54 are telescoped over the plungers 53 to allow removal of the pressed cakes. For this purpose hydraulic jacks are provided, two for each ring 54. Each jack, which is interposed between a ring 54 and a plate 52, consists of a cylinder 92 receiving a piston 93. Control valves are mounted on a block 100, one for each pair of cylinders whereby the rings 54 may be shifted one at a time successively, under manual control.

Title: Process for exploiting the by-products from the manufacture of nitrogenous compounds having an open or cyclic chain of six saturated carbon atoms
IPC: C07C51/27
Filed: 1952-07-30
Abstract: Dicarboxylic acids are made from the lower and higher boiling by-products obtained in the manufacture of nitrogenous organic compounds having one open or cyclic chain of six saturated carbon atoms by oxidizing the said by-products which also contain nitrogen atoms and open or cyclic chains of six saturated carbon atoms with aqueous nitric acid, preferably in the presence of oxidation catalysts, at moderately elevated temperatures, separating the dicarboxylic acids so formed, and converting any by-products of the oxidation process containing nitro groups into further amounts of dicarboxylic acids by heating them, preferably in the presence of strong sulphuric acid, to about 100-180 DEG  C. until nitrogen oxides no longer escape.  By-products from the manufacture of cyclohexylamine, dicyclohexylamine, hexamethylene diamine, caprolactam, o -aminocapronitrile and adipic acid dinitrile are mentioned.  The nitric acid may be of about 40-80 per cent concentration and the oxidation temperature from 35 DEG  to about 95 DEG  C.  Nitrous acid and vanadium compounds are specified catalysts. Adipic and glutaric acids are the main products, some succinic and oxalic acid also being formed.  The nitro compounds may be extracted from the oxidation reaction mixture with a solvent such as chloroform before conversion to acids.  In examples, technical distillation residues of (1) adipic acid dinitrile, and (2) caprolactam, hexamethylene diamine, o -aminocaprolactam or dicyclohexylamine are oxidized in the presence of ammonium vanadate and sodium nitrite to adipic acid and in (3) 1 - cyano - cyclopentanone - 2 obtained as first runnings in the distillation of technical adipic acid dinitrile is oxidized in the presence of ammonium vanadate and sodium nitrite, the oxidation mixture being extracted with chloroform and the extract treated with sulphuric acid to yield glutaric acid which is also recovered from the aqueous residue from the extraction.
